1ro WHOM rr MAY coNcERN':

Be it known that I, WILLAM It. Swrnnmtrou, of Peoria, in the countyvot Peoria, and State of Illinois,

have invented a new andvaluablelmprovement in-Mechanicnl Movements; and I do hereby decla-re' that the 1' rfollowing is a full, clear, and 'exact description of thecons'truction and operationof the same, reference being had to the annexed drawings making a part-of this speciicatiomn which- Figure 1 is a plan view,

'FigureZ is e. side view.

AFigure 3 isa wheelgrrith the lever-.attached,-and Figure 4 is a. cross-section of fig.- 3 at the line y g/ v'lhenature of invention consists in providing means in mechanical movements by which two revolutions are obtained for theoworking-shaft toasingle Vrevolution oi' the main shaft, and this is accomplished without., the agencyk of coge, belts, or drums; v.

Figure 3, Aofthe drawings, represents a wheel, with'handles on the periphery thereof, and it has four slotted arms, which for convenience I havvemurkcd A, B, C, and D. 'Ihe letter E, on said .last-mentioned figure, is n. lover, firmly fastened at its centre to the working-shaft of the machine, marked G. This lever E hasgtwo arms, covered with antifrictionlrollers. The arms -ere shown by the letter K on iig. 3, and lone arm and anti-v frietion rollerare shown by the same letter on g. 4. The disk, marked H,'on iig. 3, represents an enlargement of the end of vthe main shaft L, where it i's united to the wheel, but the front part of the wheel, at its centre,

isleft open in the manner shown in g. 3.

The wheel and shafts of my'device, and the relative -position of the shafts to each other, arewell repre-v sented byiig. 2-of' the drawings. Letter L, I call the main shaft, and letter G the'working-shaft. Ela'chof said shafts rests and revolves inarbor's, as shown on the-drawings, and -they `are placed in position in such manner that shaft G shall be distant from shaft L about onefourth the "diameterof the wheel inside the rim.

My device operates as follows, to wit: The motive-power is-opplied either to the wheelor main shaft, caus- 'ing the wheeland main shaftto revolve. Suppose, .when the wheelcommences its revolutions, one arm, K, on

the lever E, isin the 'open space in the centre of the wheel, the other arm K is :near 'the rim of the wheel' in slot C. The revolution ofV the whejelgradually brings the last-mentioned arm fromthe slot C to the centre of the wheel, while theother moves on itsHroll-erup'the slot B This movement is repeated by one arm passing up slotA, and the other up slot D, alternntely, thus making four half' circles. Now, asfth'e working-shaft G is attached to the centre of `the lever E, it-folloiv's thattwo revolutions ore'performed by-said-shaft while the wheel and main shnt'tareperformingone; y

The advanthges of my device are, first, it provides means for accelerating speed in machinery, whichlare r -novel to mankind and eminently useful; second, itsaves'a vest amount of frictionjn 'working machinery; third,l

it provides for overcoming to a very great extent thc diiculty of dead-points"1 iirmachinel'y; fourth, it adds to the leverage oi' machinery fullyA twenty-five per cent.,thu.-;` makingit possible'for; one hundred pounds of steam-todo the workl'which one hundred and twenty-five poundshave done when applied by any device heretd-v fore known or used; fiftlnitis exceedingly simple and cheep inconstruction. Y

lWhat I elaimas-my invention, and desire to secure by Letters Patent', is-

1. Thelever E, with its arms K, and all equivalents of the saine, constructed and, operating substantially as and for the purposes specified.

2. In combination with lever E, Iclnim.tl1e slotted \vheel'as described,` andthe vshafts L' and G'constructed tand operating substantiallysas set forth..

l '3. I claim. the mode of adjustment und arrangement o5 the shafts L and Gfherein set forth, in such man-- ner that their relative distance from each-other shall correspond to about one-fourth the diameter of the wheel. 4.' I ela-im thecombinatioii and arrangement of the various parts herein-describedend shown; for the purposeof producing accelera-ted speed in machinery. A WM.` R. SWINNERTON.'
